Objective To study the effects of electroacupuncture(EA)on gastrointestinal motility and nitric oxide synthase(NOS)positive nerves in myenteric plexus in acute exhaustive exercise rats. Methods A total of 54 male Sprague-Dawley rats were randomly divided into an acute exhaustive exercise(AEE)group,an AEE plus EA group and a control(C)group.The gastric empty rate and intestinal motility rate were measured,and histological changes of NOS-positive nerves in ileum myenteric plexus were observed with enzymatic histochemical method and image analysis technique. Results In the rats of AEE group,the gastric empty rate and intestinal motility rate were delayed but the numbers of NOS-positive neurons and expression levels of NOS in the ileum myenteric plexus significantly increased comparing with those of the C group(P＜0.01).Compared with AEE group,the gastric empty rate and intestinal motility rate were significantly increased but the number of NOS-positive neurons and expression level of NOS in the ileum myenteric plexus significantly decreased in AEE plus EA group(P＜0.01). Conclusion The findings of this study suggest that increase of NOS-positive neurons and expression levels of NOS in the myenteric plexus is one of the mechanisms of slowing down of gastrointestinal movement after acute exhaustive exercise.Electroacupuncture at Zusanli acupoint may decrease the number of NOS-positive neurons and expression levels of NOS in the myenteric plexus,and improve gastrointestinal movement in acute exhaustive exercise rats.

Objective To study the changes of cytokines in aqueous humor of patients with proliferative diabetic retinopathy (PDR)after intravitreal bevacizumab (IVB) and the correlation of these cytokines.Methods Fifty-six patients(63 eyes) with severe PDR underwent pars piana vitrectomy (PPV) with IVB pretreatment in our hospital from April,2014 to February,2015 were collected.All the patients received IVB therapy from 3 days to 7 days before PPV.Aqueous humor samples were collected at the time of IVB and PPV treatment.The concentrations of vascular endothelial growth factor (VEGF),interleukin-6 (IL-6),interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) were measured by cytoinetric bead array (CBA).The changes of these cyto-kines after IVB were analyzed by using Wilcoxon rank sum test for paired data.The correlation between these cytokines was analyzed by using Spearman rank test.Results From 3 days to 7 days after IVB,the concentration of VEGF in aqueous humor was (6.57 ± 12.29)pg · mL-1,lower than the pre-operation of (278.71 ±340.20)pg · mL-1,the difference was statistically significant (P ＜ 0.05).The concentration of IL-8 was (385.60 ± 1099.47) pg · mL-1,higher than pre-operation of(298.87 ± 1005.79) pg ·mL-1,the difference was statistically significant (P ＜ 0.05).IL-6 and MCP-1 were increased after IVB,but the difference was not statistically significant (all P ＞ 0.05).VEGF,IL-6,IL-8 and MCP-1 had an obviously relationship between each two factors(all P ＜ 0.05).Conclusion Angiogenesis in patients with PDR are regulated by a variety of cytokines,and targeted reduction of VEGF may compensatory increase the concentration of other inflammatory cytokines.

Objective Depression is a mood disorder that causes a persistent feeling of sadness,with high morbidity rates and great social impairment.Increasingly studies show the abnormalities of brain networks.We summarized the results of resting state functional magnetic resonance imaging study of depression,and demonstrated the neural loops mechanism from neuroimaing perspective.Methods The key words depression, resting state and network were searched in PubMed,CNKI and Wan Fang databases from January 2000 to December 2014.The nodes of depression related network and the alterations of cortex resting-state networks were summarized.Results 24 studies focusing on resting state network of depression were identified.40 studies based on ROI (region of interest) analysis,which included amygdala,frontal lobe,pregenual anterior cingulate cortex and cerebellum.The functional connectivity of ROIs were calculated and compared between groups.8 studies based on ICA (independent component analysis),the resting state networks were extracted and compared between groups.Two based on graph theory,the functional connectivity of whole brain were analyzed and compared.Conclusion There are abnormalities of functional connectivity among limbic system-thalamus-frontal cortex,and the changes of functional connectivity were associated with clinical symptom and drug efficacy of depression.

Objective To compare the clinical effects of combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve versus spinal-epidural analgesia in total hip replacement. Methods Fifty cases of total hip replacement were randomly divided into two groups. Patients in group A received combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve,while patients in group B received spinal-epidural analgesia. Results There were no significant differences in preoperative HR, SBP,DBP and SpO2 between the groups(P > 0. 05). Compared with pre-anesthesia data,HR,SBP,DBP in group A were significantly lower during the anesthesia(P < 0. 05). In group B,there were no significant changes in HR,SBP,DBP and SpO2 during the anesthesia( P > 0. 05). Patients′ heart rate in group A showed significant changes compared with that in group B. The differences in HR,SBP and DBP between group A and B at the same time points were significant(P < 0. 05). Superior rate of anesthesia in group B is higher than that in group A(P < 0. 05). Conclusion Combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve has limited influence on the circulatory and respiratory systems,which can be used for total hip replacement.
